Application filed October 19, 1910. Serial No. 587,804.

To all echomit may concern,

Be it known that I, Jonx L. Motion, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and use ful Im' rovcmcnts in Car-Roots, of which the fol owing is a specification.

This invention relates to car roofs, and has for its general object to provide an improved metal roof structure which shall be durable, strong, and flexible, and in which any rain or water that may be driven in over the edge of the metal roof sheets shall drain oti through the hollow carlines and discharge over the side plates of the car.

Another object is to provide improved connecting nit-ans for supporting the metal cal-lines at the side plates of the car.

Another ObJLCt is to provide an lmproved saddle or bracket for supporting the run ning board and holding together the root members at the ridge.

Still another object is to provide improved means for fastening a handhoid or other attachment to the thin metal roof sheets.

These and other objects will hereinafter more fully appear from the following description and claims:

In the accompanying drawings: Figure 1 is ii transverse sectional view of a portion of scar roof embodying a preferred form of my improvements; Fig. 2, a side elevation ot the same; Fig. 3, a transverse section of a portion of the roof at the side plate of the car, said section being taken through the center of a cal-line and showing the side plate bracket connection; F 4, a transverse section of a carline, upon a larger scale; Fig. 5, a vertical longitudinal section through the center of the car ridge; Fig. 6, a transverse section of the running board saddle taken at one side of the ridge pole; Fig. 7, a View similar to Fig. 3, but showing a slight modification in which the side plate bracket is formed integral with the carline; F ig. S, a similar view showing another modification in which the drain passage exbelow the side plate; Fig. 9, a. section of a carline showing a slight modification; and Fig. 10, a vertical sectional view of the improved means for connecting a handhold or other attachment Tto the roof plate.

According to the construction shown in the drawings, the metal roofing sheets or plates, 23, which may be of galvanized steel, are supported at their side edges upon the metal carlines, 20, which are preferably constructed of U shaped steel sections and supported at the side plates, 21, upon brackets, 27, which are preferably formed with a pocket for. receiving drainage water from the channel in the carline and discharging through a passage, 29, to the outside of the car. As shown in Figs. 1, 3. and 7. this passage, 29, is in the form of a hollow bolt extending through the side plate, 21, and which may also be used to fasten the down turned end of the cat-line cap. 22. in the modification shown in Fig. 8. the drain passage, 29, side plate and thescrew, 39". is used for fastening the end of the carline cap, 22. It. will be apparent that this side plate bracket, 27, may be formed separate from the carline and bolted thereto. as shown in Figs. 1, 3. and 8, or formed integral therewith as shown in The roof sheets, 23. are provided with down turned edges at the caves and ends of the car, and may be fastened in any convenient-manner, as by means of wire nails, while the edges of the root sheets along the sides over the carliues and at the ridge may be turned up as shown more clearly in Fig. 4. The carlines and the upturned edgesot the roof: plates, 23. are covered by the carline caps, 22. which are preferably formed with central vertical webs and sideiianges having grooves to accommodate the up; turned edges of the roof sheets, as clearly shown in 4.

The'carline cap, 22, is preferably secured to the 'carline, 20, by means of wedge keys, 35, which extend tl'irough slots. in the web of the cap and side Walls of the U shaped cal-line, whereby the cap be drawn down tightly upon its roof sheets, and be made to clamp the edges of the same between the flanges of the earline and cap. The sheets are not rigidly held, however. but are sufiiciently loose to permit of a sliding movement which makes a flexible construction and provides for, the contraction and expansion of he roof sheets and theweaving motion of the car.

Fig. 9, shows a slight modification in which the cap, 22, is secured to the csriine,

20,103 means of a clamping bolt, 35, and the upturned edges of the roof sheets, 23 are tiirned over so that any water which may in bracket. '27. leads out below the channel, a cap for covering same, a side plate bracket supporting the end of the carline, and a hollow bolt extending through the side plate for draining oil water from the carline, the carline cap being extended at its end and secured to said hollow bolt.

'[6. Ina car roof,'the combination of metal -carlines having'drain channels, metal roof sheets supported at their edges upon the carlines over said channels, carline caps covering said channels and the edges of the'roof sheets, and running board saddles having cap portions covering the edges of the roof sheets and the carline channels at the ridge and extending over the upper ends of the carline caps, and connecting means between the saddles and carlines for clamping the saddles down'upon the roof sheets.

7. In a car roof, the combination of metal carlines, a ridge pole supported on said carlines, metal roof sheets supported at their edges upon the carlines and the ridge pole, carline caps covering the side edges of the roof sheets, a ridge cap formed in sections. and covering the upper edges of the roof sheets, and running board saddles having cap portions extending over the ends of the carline caps andthe ends of the ridge cap sections, and connecting means between the saddles and carllnes for clamping the saddies down upon the root sheets.

7 rigidly secured thereto,

8. In a car roof, the combination of metal carlines having drain channels, metal roof sheets supported on the carlines-Wit-h their edges over said channels, carline caps covering the edges of said roof sheets, and a running board saddle having a portion extending down into the channel of the carline and the saddle member also having cap portions extending over the ends and forming a continuation of the carline caps.

9; In a car roof, the combination of metal carlines havingdrain channels, metal roof sheets supported on the carlines with their edges over said channels carline' caps covering the edges of said roof sheets, a ridge pole supported on the carlines, a ridge cap therefor, and a running board saddle having Webs extending down to the carline, on both sides of the ridge pole and rigidly secured to said carline, the saddle also having cap portions extending over the ends and forming a continuation of the carline caps.

10. An attachment for thin metal roof sheets, comprising a stem extending through an opening in said sheet and having a plate for the under side, a bracket or base member surrounding said stem, for the upper side of the roof sheet, and a nut on said stem for rigidly clamping the base and the under plate to the roof sheet.

11. An attachment for thin metal roof sheets, comprising a stem extending through an opening in said sheet and having a plate for the under side, a bracket or base member surrounding said stem and opening, and having a flange for the upper side of the roof sheet, a key passing through the base and the stem, and a nut for clamping the base and the under plate to the roof sheet.

m 12. In a. car roof, the combination'of a thin metal roof sheet having an opening surrounded by an upturned flange, a stem extending through said opening and having'a plate for the under side of the sheet, a brace or bracket member surrounding the stem and said flange on the upper side of the sheet, and a nut on said stem for rigidly clamping the base and under plate tothe roof sheet.

In testimony whereof I have hereunto set my hand.
